METHOD OF. CONS 7 Claims.

This invention relates to the manufacture of spools of cellulosic ribbon composed, for example, of Cellophane in various plain colors or combinations of colors as well as in many ornamental designs suitable for various seasons and occasions; and more particularly an object of'the invention consists in the method of arranging and mounting such ribbons on spools so as to preserve the ribbons, maintaining the same in a soft, pliable state so as to facilitate a more convenient and practical use thereof; a further object of the invention being to provide a spacing or filler strip associated with the cellulosi-c ribbon on the spool and between the separate windings or turns of the ribbon on the spool to act as a carrying or supporting agent for a fluid or compound to maintain the ribbon in its soft and pliable state; a

further object being to provide an embossed or characterized filler or spacer strip of the character described which will operate to emboss or characterize the Cellophane ribbon when wound on the spool to give other characteristics and structural features to the resulting ribbon; and with these and other objects in view, the invention consists in a device of the character described, constructed in accordance with the method more fully hereinafter described and claimed.

The invent-io-n is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate reference characters in each of the views, and in which:

other adaptation of the invention.

Fig. 3 is a partial section on the line 3 of Fig. 2 on an enlarged scale, exaggeratively illustrating the embossing effects upon the resulting ribbon, and I Figs. 4, 5, 6 and '7 inclusive, are detail plan views showing different methods of applying the softening solution or agent to the spacing or filler strip.

In the construction of spools of cellulosic ribbon such as Cellophane-ribbon, it has been commonly experienced that the ribbon, after laying around in store rooms, on the counter, etc., as well as laying around in the home prior to uses or intermittent uses thereof, that the ribbon has become stiff and hard which has materially affected the use thereof and in fact has rendered ness has also caused the ribbon to become brittle parts of my improvement are designated by suitable the use objectionable. This stiffness ,or hardand to rupture more readily, especially in the process of time.

It is one of the purposes of my invention to produce ribbon spools of the character under consideration wherein a filler or spacing strip is employed which is treated with a solution or agent which will operate to maintain the separate windings of the ribbon on the spool in a soft and pliable state for a long period of time. While it is conceivable that the outer winding of the ribbon may become somewhat hardened over a period of many months, the inner or covered windings of the ribbon upon the spool will be maintained in the desired soft, pliable state.

In Fig. 1 of the drawing, Ill represents the usual paper, cardboard, or other coreof the spool upon which the filler or spacing trip H and cellulosic (Cellophane) strip l2 are wound. The strip H is preferably wider than the ribbon l2 so as to guard the edges of the ribbon in the handling of the spool and also to effect a'better seal of the ribbon within the respective windings, it being understood that the strip II is of softer texture than the Cellophane strip.l2, and in a tight winding, the Cellophane strip would not be exposed or visible at the sides of the resulting spool.

The Cellophane strip I2 is shown as being plain in cross section "for the purpose of simplifying the illustration, but in actual practice the side edges of the Cellophane strip or ribbon are folded inwardly to give strength thereto.

In the construction shown in Fig. 1, theentire strip 1 I is saturated, sprayed, or otherwise treated with a solution consistingbf water and glycerine with a sufficient amount of glycerine in the solution to leave a deposit of the glycerine on the strip ll, maintaining said strip soft at all times. In windingthe strips II "and I2 one upon the other in forming the spool, it will be understood that the separate coils of the strip l I will engage upper and lower surfaces of the windings of the strip l2, whereby the close Contact of the strips will enable the glycerine tobetransmitted to the .Cellophan'e strip, preserving it in the soft and pliable state which is desired. 'It will of course be understood that the degree of treatment of the strip II will be regulated so-as to prevent excessive saturation of the strip I2, but this can be controlled in many ways in the preparation and treatment of the strip 1 I. This strip l I may be composed of various kinds and grades of paper, and particularly paper having sufficient absorbin properties to absorb and hold the solution therein. In the construction shown in Fig. 1, the strip ll has a plain or finished surface, and in using a strip of this type and kind, the ribbon l2 will be maintained in a smooth state or condition at all times.

It isanother feature of my invention, however, to provide a spacing or filler strip lla, as is .shown in Fig. 2 of the drawing, which is of a crinkled, embossed or otherwise characterized structure, the crinkling, embossing or the like being illustrated diagrammatically at l3. With an arrangement of this type, it will be understood that the resulting ribbon l2a will have thereon, when removed from the spool, embossings as at M, thus breaking down the flatness or evenness of the ribbon and giving added characteristics thereto.

It will be readily understood that by reason of the contour of the strip Ila and the fact that the strips Ila, lZa are wound tightly one upon the other on the core lOa of the spool, the irregularities will be transmitted to or formed in the strip l2a. While in the illustration in Figs. 2 :and 3 of the drawing, markings from one layer or turn of the strip l l a are shown, it will be understood that markings of another layer or winding of this strip will also act upon the strip I211, as each turn or winding of the strip Hat is disposed between two turns of the strip lla. .Another method of carrying out the same effect as the strip II a, is indicated in Fig. '7 of the drawing wherein the strip l lb is provided with a series of apertures or perforations l5. While different forms of perforations are shown, it will of course be understood that these perforations may be all of the same outline and may be made smaller and larger to provide predetermined effects.

In Figs. 4, and 6 of the drawing, I have shown other methods of treating strips of the type and kind illustrated at l l, I la, Hb in the application of the solution or softening agent thereto. In Fig. 4 of the drawing, l6 represents any suitable strip of this type and kind which has a series of transversely arranged and longitudinally spaced deposits of the solution as at IT, leaving therebetween, untreated sections l8. In Fig. 5 of the drawing a strip l 6a is shown having two longitudinal ribbon-like deposits of the solution I la arranged adjacent the side edge portions of the strip, leaving untreated longitudinal sections l8a. In Fig. 6 of the drawing, a strip l6b is shown having a combination of transverse deposits l9 and longitudinal deposits 20. It will of course be understood that any desired arrangement, contour or design of the deposits may be provided by simply constructing the applicating means to suit the effect which is contemplated.

As another feature of the present invention, it should be noted that in addition. to the saturant for maintaining the cellulosic material soft and pliable, the spacing means. may have incorporated therewith, a suitable aromatic compound orcompounds adapted to impart a desired scent or odor to the cellulosic material. Such an arcmatic or volatile compound is preferably incorporated in the saturant, and it will be apparent that the entire area of the spacing means or strip may be treated with both the saturant and the aromatic compound. On the other hand, the desired effect may be produced by including the aromatic compound at intervalsalong the spacing means. By way of illustration in Figs. 4 and 6 of the drawing, the transverse treated portions l'l and I9 respectively. may be. alternately treated with thesaturant aloneandwith the. combined saturant and aromatic compound. It will be understood, however, that the precise amount and arrangement of the aromatic compound would depend entirely upon the particular effect desired in the cellulosic material.

While the improved spacing strip has been shown in the drawing as associated with a relatively narrow ribbon, it will be understood that a spacing strip made in accordance with the present invention may be employed with ribbons of any width. It will be apparent in this connection that the spacing means is also applicable for use with sheets of cellulosic material, such for example, as sheets used in wrapping goods and small articles. A primary purpose for using the spacing means in this connection, would be to impose some predetermined surface irregularity to the separate sheets while at the same time maintaining the cellulosic material soft and pliable. It will be apparent, however, that the use of a suitable aromatic compound in this connection is likewise of primary importance to produce a scent or aroma on the cellulosic material. In this connection, it will be noted that the aromatic compound incorporated may produce a generally pleasing scent, or on the other hand may be characteristic of the particular article which is to be wrapped.

As a still further feature of the present invention, it should be understood that when a spacing strip treated with a saturant in the manner previously described, is wound intermediate successive windings of a cellulosic ribbon, there is a slight adhesion between the saturant of the strip and the ribbon which is diagrammatically shown in Figs. 1 and 2 of the drawing. This slight adhesion, while permitting the intentional unwinding of the ribbon, tends to materially decrease accidental unwinding and especially the highly objectionable side-slip of the ribbon and spacing strip which is often experienced and which often occurs in conventional ribbon spools.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
